1 1 1 0 0 0 1 1
(128 * 1 ) + (64 * 1) + (32 * 1) + (16 * 0) + (8 * 0) + (4 * 0) + (2 * 1) + (1 * 1)
128 + 64 + 32 + 2 + 1 = 227
i guess this will help.....
To convert the decimal number -19 into the signed magnitude binary system, first convert the absolute value, 19, to binary. The binary representation of 19 is 10011. In a signed magnitude system, the first bit indicates the sign (0 for positive, 1 for negative). Therefore, the signed magnitude representation of -19 in an 8-bit format is 10010011.
Signed integer is any integer that carries negative sign while unsigned integer is any integer that carries positive sign
The largest unsigned integer is 26 - 1 = 63, giving the range 0 to 63; The largest signed integer is 25 - 1 = 31, giving the range -32 to 31.
When decoded, that binary says: «“
Binary multiplier is taking numbers and using multiplication and division. This is used in math.
The highest unsigned integer is 255; The highest signed integer is 127.
A 5-bit binary counter, interpreted as an unsigned integer, has a range of 0 to 31. Interpreted as a two's complement signed integer, it has a range of -16 to +15.

Actually, that answer is incorrect. Binary is used to hold information. However, without a context, the information can only be translated as a number. There are two types of binary integers (ironic, right?). The first type is called unsigned. The second type is called signed. If you have an unsigned binary integer, the number can only be positive. If you have a signed binary integer, the first number indicates the sign of the number (and ONLY the sign. A position cannot mean both a value AND positive or negative). A '0' in front means positive, and a '1' in front means negative. So, if the number in question was an unsigned integer, it would have a value of 1024 + 64 + 32 + 16 + 4 + 1 = 1141. If the number in question was a signed integer, it would have a value of (-1)*(64 + 32 + 16 + 4 + 1) = -117.
To get the 2s complement, change all 1 bits to 0s and all 0 bits to 1s, and add 1 to the result. So the 2s complement of the 8-bit binary number 10001011 is the binary integer 01110101. If you want that in decimal, then remember that each place value column is twice the value of the place value column to its right, and the rightmost place value column for an integer is 1. Thus 01110101 in decimal is 64 + 32 + 16 + 4 + 1 = 117 (And 10001011 as a signed 8-bit binary integer represents the decimal integer -117.)
An unsigned integer cannot be negative. It has a maximum positive value twice that of a signed integer. Max signed: 128 Max signed: 256 I could be off by one there, though.
Signed integer is any integer that carries negative sign while unsigned integer is any integer that carries positive sign
The largest unsigned integer is 26 - 1 = 63, giving the range 0 to 63; The largest signed integer is 25 - 1 = 31, giving the range -32 to 31.

signed integer means that it has a sigh (+ or -). Using another words you say that signed variable can be positive as well as negative. unsigned variables can be only positive.
